- Developed Hydraulic Variable Stiffness (HVS), a simple and lightweight variable stiffness mechanism.
- HVS uses a peristaltic pump to control stiffness by adjusting the volume of the tail internal void.
- HVS uses water in the robot's operating environment to control the stiffness, so no external devices are required, and the robot's buoyancy does not change as the stiffness changes, making it stable.
- Lower tail stiffness for lower tail driving frequencies and higher tail stiffness for higher tail driving frequencies to maximize swimming speed by optimizing the optimal tail stiffness for each tail drving frequency.
- Reduce tail stiffness to minimize the turning radius and maximize the turning angular velocity for efficient sharp turns.
- The tail stiffness can be controlled to optimize different swimming motions, which is expected to make it commercially viable for various underwater exploration missions.
